You can notify the newly created sysop on their talk page, and give them some good advice too, by doing this:

{{subst:Template:AdminWelcome/en}}
"personal remarks" ~~~~

You should then mark the candidacy ([[Meta:Requests for adminship/newlyMintedAdmin]]) as successful by adding {{subst:closed request}} at the top to gray it out and </div> at the bottom of the subpage to let folks know it's over. You should explain your rationale if there might be any doubt about consensus. Save the change, untransclude it from Meta:Requests for adminship and add it to Meta:Requests for adminship/Archives by linking to it at the bottom.

You will see that some candidacies have special circumstances you may want to note (second try, failed, request for 'crat, reconfirmation by the community, etc.).

Local Administrators

Add and remove the Translation administrator and the flood flag from themselves. Please remember to remove the flood flag when you are finished, or only assign it as a temporary flag from the start.
